WordPress (I use this for my blog) has an interesting Stats feature on the WordPress Dashboard (the main control panel). You can see what terms people search on to get to your site. Like, today, someone searched for “Katie Kelly’s Real Name” and landed on my blog.
I can also see what search engines people use. And so I see that yesterday someone used Google to translate my blog into Japanese. Here it is. If you speak Japanese, please let me know if there are any typographical errors!
